Coffeescript can be compiled into concise and efficient JavaScript to clearly see the content being compiled. It can be fully compiled into functional JavaScript without any type of Runtime Library. The syntax provided by coffeescript allows you to take full advantage of the powerful functions of JavaScript, and requires only a small runtime overhead.

Advantages of coffeescript:

● Provides a relatively simple syntax to reduce sample code, such as parentheses and commas
